1) The first equation is a line if you were to graph it. The only way to “simplify” is to get rid of the fractions. Multiply everything by the LCD, and that would be 15. Your final answer will still be an equation, just without fractions.

Do the same thing for the second equation, and you should be able to solve for x, which does have one specific answer.

2) I wand YOU to look up the rules for exponents.

3) This is a line, it goes through the origin, an the rise over run is one:four

Those notations are defined in your glossary

4) When factoring, look at the last number. What two numbers multiply together to give you that number, AND add or subtract to give you the middle number?

One and 14 of course, both signs are positive, so (w+14)(w+1)

Zen? That is not math, that is:

a school of Mahāyāna Buddhism notable for its emphasis on practice and experiential wisdom—particularly as realized in the form of meditation known as zazen—in the attainment of awakening. As such, it de-emphasizes both theoretical knowledge and the study of religious texts in favor of direct individual experience of one’s own true nature.

A broader term is the Sanskrit word Dhyana, which exists also in other religions in India.

The emergence of Zen as a distinct school of Buddhism was first documented in China in the 7th century CE. It is thought to have developed as an amalgam of various currents in Mahāyāna Buddhist thought—among them the Yogācāra and Madhyamaka philosophies and the Prajñāpāramitā literature—and of local traditions in China, particularly Taoism and Huáyán Buddhism. From China, Zen subsequently spread southwards to Vietnam and eastwards to Korea and Japan. In the late 19th and early 20th centuries, Zen also began to establish a notable presence in North America and Europe.

2/5x – 1/3y = 1

you can make 2/5 into 2/3?

and leave 1/3

(im really bad at maths) sorry this hasnt helped has it?
